In this episode, Glen Whitman discusses Economics of the Undead: Vampires, Zombies, and the Dismal Science, a book he co-edited with James Dow. Glen is an economics professor at California State University and, unlike most academic economists, he moonlights as a TV writer. He first wrote for the TV show Fringe and now writes for the soccer spy drama, Matador.
The book’s website provides the following description:
“Whether preparing us for economic recovery after the zombie apocalypse, analyzing vampire investment strategies, or illuminating the market forces that affect vampire-human romances, Economics of the Undead: Zombies, Vampires, and the Dismal Science gives both seasoned economists and layman readers something to sink their teeth into.
Undead creatures have terrified villagers and popular audiences for centuries, but when analyzed closely, their behaviors and stories—however farfetched—mirror our own in surprising ways. The essays collected in this book are as humorous as they are thoughtful, as culturally relevant as they are economically sound, and provide an accessible link between a popular culture phenomenon and the key concepts necessary to building one’s understanding of economic systems large and small. It is the first book to combine economics with our society’s fascination with the undead, and is an invaluable resource for those looking to learn economic fundamentals in a fun and innovative way.”
Among the topics covered in the discussion are helpful hints such as how to meet the vampire man of your dreams, to choose what to bring on your trek across the zombie-infested wastelands you once called home, and to rebuild civilization after the undead apocalypse.
Human capital will be particularly helpful in the zombie apocalypse; it has immense value and goes wherever you go. Doctors are often depicted among the survivors of the zombie apocalypse, possibly because survivor groups would rather recruit a doctor than kill him. There’s an analogy to pirates, who would press valuable seamen like surgeons or carpenters into service rather than killing them (for more pirate economics, check out Peter Leeson’s The Invisible Hook).
Among the more unexpected chapters of the book is “Killing Time: Dracula and Social Discoordination,” by Hollis Robbins. Robbins connects the infamous Transylvanian villain’s ability to distort his victims’ senses of time to date- and time-keeping standards that some nations had adopted while others had not at the time the book was written.

In this episode, Nathan Smith discusses the economics and history of migration and migration restrictions. Nathan is an Assistant Professor of Business Administration: Finance and Economics at Fresno Pacific University and regular blogger at Open Borders: The Case.
We start the episode by discussing the economic impacts of Nathan’s own migration to Fresno. Students gain, as he adds to the supply of economics professors, other economists might lose from his competition in labour markets, people looking for parking near the University might lose, as he slightly reduces the supply of available parking spaces, and property owners gain from his demand for housing. In general, anyone Nathan transacts with gains from the transaction, while those who he competes with may suffer some slight loss.
The big slogan among open borders advocates is that a significant reduction in migration restrictions could “double world GDP.” Nathan’s own most recent estimates show about a 91% increase world GDP, mainly because people would move from places where they can earn very little (e.g. places with dysfunctional institutions) to places where they can earn quite a bit more (e.g. places with well-functioning institutions, complementary factors of production, highly developed networks of specialization and exchange, etc.). There are complementarities between human capital and unskilled labour. For instance, great managers are more productive when there are many workers to manage, and the workers are more productive where there are great managers.
Nathan’s estimates indicate that as much as 44% of the world’s population could migrate under open borders. This may seem high, but even conservative estimates would put the number of migrants in the billions. While migration would be hard for the first few migrants, diaspora effects would start to make the process smoother and more desirable. In the 19th century, when international migration was less restricted and more common, migrants would form communities within their new countries: there would be a Polish neighbourhood, an Irish neighbourhood, an Italian neighbourhood, etc. These diaspora communities would function as gateways to the new culture, giving people a place to settle while they adjusted to the language and culture of their new country.
Today, with the exception of migration within the EU, there are no countries with open borders. While migration is somewhat easier for high-skilled workers, there are still many barriers. People call high-skilled migration “brain drain,” but that is really a perverse way of characterizing it. Are workers’ “brains” their countries’ property? Are they to be kept as forced labourers for their countries’ benefit? In addition, the idea of brain drain is empirically questionable. If getting high skills is a ticket to a better life in a different country, the possibility of migrating increases the incentive to gain high skills, thus offsetting the loss of those who eventually emigrate.
When people can migrate, or “vote with their feet,” this puts competitive pressure on governments. For instance, governments’ ability to institute very progressive taxation is curtailed by high earners’ ability to move elsewhere. That the Soviets had to build a Berlin Wall to keep their citizens from leaving shows that the possibility of exit was threatening to the Soviet government.
Some restrictionists compare immigrants to the Visigoths in the Western Roman Empire. That is a poor analogy to modern migration, as the Visigoths migrated as a complete political entity.
Not only do immigrants assimilate into the existing industries, they are disproportionately entrepreneurial, founding new industries wherever they go. Nikola Tesla, Andrew Carnegie, Sergey Brin, and Elon Musk were all immigrants. During the era of open borders, many of the innovations (such as Henry Ford’s assembly line) were designed to be complementary with all the low-skilled labour made available by migrants. Much of our modern technological development is focused on economizing on low-skilled labour, but low-skilled labour is only artificially scarce in wealthy countries. Many basic tasks that high earners do for themselves could be contracted out to low-skilled migrants. Childcare, for instance, could be very inexpensive under open borders; skilled parents would not need to leave the workforce to raise their children.
Nathan sees hope for more open borders in the future. Migration restrictions are contrary to people’s consciences, which makes them difficult to enforce. This may slowly erode the restrictions. Furthermore, Christian churches are essentially supportive of open borders. There is hope for the world in moving towards open borders, but it will require moral will.

The minimum wage is a contentious issue among economists, and yet it enjoys near-universal support among the public. In my view, public views of the minimum wage are simply the result of a lack of careful thought by most people. Daniel Kahneman’s theory that people, when faced with a difficult question, substitute a simpler question that they can easily answer, applies particularly well in this case. People answer the question of whether they would like people to earn more when the real question is whether government should mandate higher wages (I first heard this argument from Bryan Caplan on EconLog).
A purely empirical argument for or against the minimum wage is methodologically wrong-headed because empirics do not speak for themselves. Sound theory must be the economist’s first tool in understanding the effect of a policy such as the minimum wage.
Before we can understand something like the minimum wage, we must understand the role of prices in allocating factors of production to their various uses. The price of a factor signals to entrepreneurs that that factor is scarce, that it is needed elsewhere in the economy, and that the entrepreneur who can reduce his usage of relatively more scarce factors in favour of relatively less scarce ones can earn profits, while entrepreneurs who fail to do so earn losses. I give the example of a sandwich shop during an oil boom; the high price of labour caused by the oil boom leads the sandwich shop to substitute away from labour in various ways.
The oil boom in my illustration is irrelevant to the story. The sandwich shop would adapt to an increased price of labour no matter what caused it. If the cause is a minimum wage law, the people no longer employed making sandwiches are involuntarily unemployed rather than finding employment in some other industry.
Minimum wage opponents sometimes get into trouble when they draw supply and demand curves to illustrate the impact of the price floor. The problem with this is that supply and demand diagrams come with built-in assumptions that do not hold true in the case of labour markets. Low-skilled labour is not a homogeneous quantity being sold in a centralized market. The simple supply-and-demand story does not capture all the effects of the minimum wage. For instance, firms substitute between different sorts of workers affected by the minimum wage. In addition, the other terms of employment contracts can change in response to a minimum wage law, such as training and benefits.

In this episode, Diana Thomas discusses the relationship between the Virginia School of Political Economy and the Austrian School of Economics. Diana is an Associate Professor of Economics at the Heider College of Business at Creighton University.
The Virginia School is a branch of public choice, the application of the tools and techniques of economics to the study of political actors. The Virginia School’s founders, James Buchanan and Gordon Tullock, were the first to systematically apply a rational choice framework to the study of politics in The Calculus of Consent.
Two assumptions commonly made by neoclassical economists are the “benevolence assumption” and the “omniscience assumption.” The benevolence assumption is implicit in normative analysis of what governments “ought” to do, as this assumes that political actors are motivated to maximize the common good rather than pursuing their self-interest. This assumption is challenged by public choice economists. The omniscience assumption is at play in economic models that depict the economy as being in equilibrium, whereby nobody is misinformed of or surprised by economic reality. This assumption is challenged by Austrian economists.
As Diana states in her paper, Entrepreneurship: Catallactic and Constitutional Perspectives, “both Buchanan and Tullock reference Mises’ Human Action as the central reference for their understanding of methodological individualism.” The Virginia and Austrian schools also share common understandings of rationality and of self-interest.
Diana draws a parallel between Israel Kirzner’s distinction between calculative and entrepreneurial action and Buchanan’s distinction between reactive and creative action. While calculative or reactive action consists in simply responding to known incentives and constraints, entrepreneurial or creative action consists in envisioning a future that is different from the present and in acting on that expectation. Kirzner applies the concept of entrepreneurship to businessmen seizing anticipated arbitrage opportunities in the market. Buchanan applies the concept of creative action to political actors attempting to reform constitutional rules.
Buchanan conceives of constitutional rules as being made behind a “veil of uncertainty” since it is beyond political actors’ ability to predict in precisely what situations the rule will be applied, and whether their own self-interest will be served or hurt in those situations.
Diana believes that political action is more entrepreneurial than most economists recognize. But while market entrepreneurship is guided by profit and loss towards those processes that best serve consumers, political entrepreneurship has no such guiding principle. Political entrepreneurs may innovate in ways that actually harm their constituents, but these innovations may nonetheless thrive and endure.
Poll numbers and bad press can motivate political actors, but these signals may not conform to the actual impacts of the policy. Good policies are often derided as evil, while bad policies are often popular. A US President can boost his popularity by declaring war, but US military ventures have a terrible track record in terms of their ultimate consequences (see Chris Coyne’s After War). Market innovations such as Lyft and Uber clearly benefit consumers, and yet there has been a political backlash against these popular businesses.
Public choice economists recognize that voters are “rationally ignorant,” since becoming informed about issues is costly, while the benefit is only manifested in better policy if the specific voter happens to be the swing vote in an otherwise tied election. Given these incentives, it would be irrational to be informed about policy, so it’s surprising that so many people vote at all. Diana explains it in terms of “expressive voting.” Voters vote because they want to express their views, not because their vote is particularly potent in shaping political outcomes.
Diana argues that policies aren’t particularly strongly affected by who is elected to office, rather they stem from institutional incentives. The median voter theorem demonstrates how, under plausible conditions, politicians attempt to please the most people by converging to a centrist policy. Another theory says that policy is not directed primarily by elections but by the lobbying efforts of special interest groups (see Olson). Since these groups get concentrated benefits from preferential policies, they have a strong incentive to agitate for them. Those who pay the costs of these policies (usually consumers) have only a small incentive to agitate against them, as the costs are dispersed among a great number of individuals.
Specific examples of policies made for the benefit of concentrated special interests are the US sugar quota, and Canadian customs duties charged for the importation of dairy products (leading to absurd cases of cheese smuggling).
